Match the following phases of stellar evolution to its characteristic. black hole
red giant
black dwarf
brown dwarf
white dwarf

does not undergo hydrogen fusion

has an outer shell of burning hydrogen
and a core of helium

a white dwarf that has lost all its energy

has a core of carbon that is not massive
enough to fuse

formed from the collapse of a white dwarf beyond 1.5 solar masses

ice to water 1 water to vapour 2 latent heat

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
